To all whom it may concern:

Be .-it,.known that 1,,CHARLES T. LIBBY, a citizen ofthe United States,residing at Portland, in the county of Cumberland and State v i I ofMaine, have invented certain new. and useful improvements inLinotype-Machines;

[,cleai', full, and exact description of the inven- 5 {.tionj, such aswill enable others skilled in the. m art Ito which-it appertains to makeand use Ithesaine. 1 F 'Bhis invention relates to improvements inmaibhines of the general character of the socal fed kif lviergenthalerlinotype -'machine I 5 shown and described in Letters Patent of theUnited States N 0. 436,532, dated'September 16, 1890.

It relates to means for reciprocating the assembling-elevator byautomatic actuating 2o mechanism set in motion by the operator each timeit acts.v i

It also relates .to means for reciprocating the assembling-elevator byautomatic actuating mechanism that runs continuously and 2 5independently of the operator.

' It also relates to means' for changing. the machine from the formerclass to the latter and back again.

It also relates to means for controlling the go automaticactuatedmechanism and for bringing it into action at the will of the oper-.ator. 1 i It also relatesto certain details of construction hereinafter,described and specifically 5 explained. f

I he existing machine is started b the linedelivery carriage beingreleased b the putting up of the assembling-elevator, which the operatordoes by a hand-lever each time he 0 has assembled a matrix-line, and themachine automatlcally stops after casting the line thus sent up unlessthe next line has already been sent up, in which case the startand-stopmechamsm of the machine is thrown out and its main driving-shaft in-.

stead of stopping runs continuously. By my. improved mechanism theassembling, elevator is putu automatically and is either set inoperation ythe operator each time he 'hasassembled amatrix-lineor at hisoption,

thel-ine-delivery-oarriag'e shaft on its return throu h intermediatemechanism starts the J assem ling-elevator, thus making themachine'constant running irrespective of "the I Y Y enough to keeptheifriction-diskfroinwcom- L ng off and allowingjus't'plaj enoughonrthe i-operator. e In the. ;drawings herewith-accompanyingSpecification of Letters Patent.

' and-TI do hereby declare the following to be a bling-elevator foroperating said releasingbalancing-spring, and P the keyboard-drivingshaft. the same and operate. in substantially the idly-thereto afriction diskh large diameterfor .thel sake. ofgreater efl'i- Patented oafa, ises.

F ig- 2.is a

These parts may be substantially same, manner as in theaforesaid Mergenthaler machine.

In carryin out my invention I substitute '5 for the hand eon theright-hand-end of the assembling-elevator lever and T attach, rig- Inthe end of the lever I fix a stud 2, on which'I place a counterpartfriction-disk 3,1nadeipartof a too pulley and driven constantly by abelt 4 om a grooved hub 5 on'the. shaft used to drive the keyboardconnections, asinthe existing machine. Thedisk-faceLI: make ofciency,and the neck or :hubibetwe'en' the disk portion and the. pulley ..end.'.-I .-make small to adapt it to the forked lever, herein; afterdescribed,; In the endof= thastmLI place a capSc1'eW.=.-fi, 'with' a;head large out of action.

square-cornered, so as to be nicely held by the angles of the two rodsdescribed below.

I attach to the forked lever two spiral springs 10 '10, one on each sideof its stud and both anchored to the keyboard. The front spring 10 Imakeminutely adjustable v by means of a nut 11, having a notched diskheld at any. desired point by aflatspring 12, screwed to the top edge ofthe lever and. adapted to fit into the notches, this nut work-' -ing ona threaded hook 1-3, passin through a plain hole in the lever, with t espring hooked thereon. The stren th of these two s rin s I adjust sothat'tlie front oneis htIy more efficient than the back one, the

difference being just enough to make the fric- I tion-disks bite enoughto raise the assembling-elevator and at the end of the trip bring backthe front rod, as hereinafter described. When thus adjusted, theslightest obstruction or the weight of the operators hand on theassemblin elevator is sufficient to make the fIlClJlOIl-(llSkd slipuntil the obstruction is removed. I I

As an aid to lightness of movement and for additional adjustment to theweight of different-length matrix-lines I retain the assembling-elevatorbalancing-spring and its connections as in the existing machine, onlyate taching it to the assembling-elevator-lever shaft at a shorterradius, so as to have its tension more uniform over the differentpositions of the assembling-elevator and making it stronger, so asrnotto reduce its. efficiency when I reduce its working radius.

Through the keyboard, back of the space- "band bar and above thespace-band lever, I

extend right and left two rods 14 -15, partly resting in their holesthrough the sides of the keyboard and partly supported by spiral Ysprings, two each, all anc ored tothe t6p edgesof the keyboard sides,the front-rod springs 16 16 extending from their anchor age downward andleftward to their points 9 attachment to the rodand having strengthenough only. to:pro1n tly shift the front rod to the right when re easedby the key-lever below mentioned, the back-rod springs 17 17 extenrlihjgfrom their anchor age downward and rightward to their points 0attachmentrto the rod and having strength .i

enough not merely to shift the back rod to the left but also to )ull theback end of the forked lever to the left against the preponderate forceof .its tension-spring. The right-hand end of both rods I bend downwardin a right-an led hook and arrange them to hook over t e top edge of theback end of theforked lever. The laft-hand ends of the two rods areadaptedto be operated the front one by a key-lever, the back one-bytheline-delivery shaft, as below described" The left-hand end of the backred I bend at slightly less than right angles, reaching up;

ward and slightly backward, so as to engage;

an eccentric screw 18, which I place-births" end of the line deliveryshaft or hub-of the v linedelivery lever, on the top edge and slightlyto the leftof the'center when the shaft is in its rightward position, sothat the last rightward movement ofthe stud will rise' the back rod tokeep it from range to rest lightly on top of the bracket belowmentioned, and on the top of the red I cut a notch 14, ada ted to beengaged. by the back end of the eydever 21, pivotally mounted on thebracket, the front end reaching to a point convenient to he touched andpressed down bythe operator. 1 The back end of the key-lever is providedwith a spring 22, tending to pull it down into its notch in the frontrod. Also at the left end I place two spurs, one, 23, reaching u ,wherethe 0 erator can conveniently pus 1 it to the let, and thereby throw offthe power and latch the front rod over in any emergency, the other, 24,reaching'downward and beveled downwardly and leftwardly, the face of thebevel adjusted to lie in the path of an exten sion 25, which I place onthe assembling-.ele-

vator lever when the front rod is to the right.

The extension I fasten to the lever by set screws in slotted holes, sothat the -extension can be adjusted upward or downward to the point thatwill throw off the friction-disks just-"as the assembling-elevatorarrives up.

the keyboard is adjusted to "prevent the rod I and its bevel facepassing too far to the right.

The bracket 27, which fastens to the frame,

of the machine, preferably having an arm at the bottom end reaching tothe right, so as to fasten by the same screws that hold the keys boardin lace, is provided withla' spur 28, reaching ownward, opposite and tothe-right of the beveled spur on the front rod,so placed that as theextension goes up it passes paral- Tbpin 26 through the front rod to theleft of.

lel with and close to it, and thus is adapted to take the side thrustand insure uniform action when the extension enj ages the bevel face andforces the front rod hack to the left, A similarspur 29, reaching 11ward t right of the back end of the rey-le close to it, is adapted totake the pul the assembling-elevator'l 'pivotally mount a latch47,adaptedto latch under a corner of v the assembling elevator when in itshigher position and, hold it up. Abovesaid latch I lace. a fiat springt8, tending to hold said atch inengagementl Nearthe bottom of I .theframe l-plvotally mount a lever 49, with 'one end adapted to engage saidlatch adversely to said spring, the other end'carrying anantifrictionroll 50, en aging a cam 51, which I place on the endo theline-deliver shaft. The arm of the lever carrying the r0 1- is offsetbackward and leftward in order to bring it'into a"wor king relation withsaid shaft. Said cam I make with two faces, one adapted to hold thelatch clear of'the elevator, the other to hold it from turning too far,

"underthe elevator. The step between these two faces I place so as toact at themoment ravity, the friction-disks apart,

when the lineof matrices hasqr'pass'ed clear of the elevator. Thisdevice is additional to the assembling-elevator hook on the existinmachine, wh ch [add byreason of the lia ility ofthe lattervtofslip ofl,I

Theinachi' e thus constructed may be op ated in three. w aysi First,when the operator touches the key every time a line is ready. Inthiscase the machine is in ready osition' whenthe'front rod islatched tothe left, the backrod held to the right by the eccentric screw, theelevator stayin down-by iield apart by the frontjrod. The operatortouching the key when his line isr'eady raises the back end of the keyleve'r," which-releases the front rod and that in turn. releases theforked lever,.

which thereupon presses the friction-disks to,

gether,f carry1ng the elevator up. As the elevator reaches its upwardlimit the needleJ hits the iilovable 'pin in the line-delivery carriage,which in turnengagcs andlraise's the 4 line-delivery carriage latch,releasing it. At

the same instant the extension on the assembling elevator lever comes tohearing between the beveled lug on the front rod and the straightlugonthe bracket, thereby forcing the front rod to the left and lettingthe fricmatrices has passed out of it.

tion-disks apart, The elevator stays u supported byits latch "and hookuntil the ine of At this point the-releasingrba'r knocks off theassembling elevator hook and the cam throws out its latch ,releasing theassembling-elevator,which falls by gravity, its'fall-jbroken by itsbalancing-spring, as In [the existing machine-l The eccentric screw'ispassing an idle course with the back rodf left free, which thereupon ispulled to the left b'y -itssprings-enga i gthe the main; to the left'efrod. All parts are now again in readyposiscope of my invention andlikewise the auxsembling-elevator lever the key-'leverdropped i into itsnotch, latching it. As the line-de- 7io livery'shaftreturns, theeccentric screw en:

ages the back rod, pushin it to the ri' ht and eavi'ng'theforked'leverhe (1 only byt e front tion. '75 The second method ofoperation is when 1 the operator hits the key before the -line-de liverycarriage gets back. At such time the back rod is to the left and;holding the friction-disks apart, as the eccentric screw is 80 away fromthe backrod; The 0 erator touches'the key, raising the back en of thekey-lever. The front'rodspringsto theri ht; but the friction-disksremain apart, eld' apart by the back, rod. This situation con 85 tinuesuntil theline-delivery shaft returns. The eccentric screw then engagesthe back rod, forcing it to the right and the elevator starts up. Thesituationnowis the same as if the elevator had been released by touchingthe key with the line-delivery shaft back.

The third method of operation is when the key-lever is locked out,therebyleaving thefront rod idle to the right, except when the 1assembling-e1evator-lever ext'ension holds it 5 to the left. ,When theelevator starts down, i the elevator-lever extension passes down-and thefront rod passes to the right immediately, 'not being latched by thekey-lever, which is 1 too locked out. This leaves the friction-diskcontrolledonly by the back rod. The opera- -tion under this conditionresembles the-sec lever, thereby bringing the front rod. again intoaction, by which step an instant change to to the first "method ofoperating the machine is effected. i f e The scope of this ap lication,generally speakingis (1) friction- 1sk adapted toraise t eassembling-elevator; (2) var ing form ofmy devices for coordinating tiieelevator-.7 raising mechanism to the general machine movements ada tedto-mechanism driven from a constant y rotating pulle (3) vary-v ing formof my double-controlfing devices 15 adapted like 2; (4) device forelevator-raising mechanism driven from a constantly-r0 .tating pulleyadapted to disconnect it .when

the elevator has been raised; (5) varying form of device for locking theelevator up until cleared by the matrix-line.- "An equivalent meanswhich may be substitute forthe spe cific devices herein shown for thesepurposes,- all of which are equally within the spirit and I iliarymechanism for regulating and controlling the main features of myinvention may be greatly varied, and I desire not to be lim ited inthese respects otherwise than as specifically setontin the claims.

The advantages of my improved machine are as follows: It is optionalwith the opera-' tor to haveit either a constant-running or astart-and-stop machine. 'Iheformermethod is valuable to the large numberof operators who are able toset news-measure to the full speed of themachine and who are thus saved 1;

e labor and nervous strain of putting up the assembling-elevator andwatching the I ,thermore, operators who are 'otherwise'un movement ofthe machine for the proper time of doing so,- in fact having nothingleft to do but to be sure their line is set before the elevator goes upand then enjoying an instants relaxationand an opportunity to glance'atco ywhile the assembling-elevator automaticaly goes up and returns.Furable to set lines to the full speed of the machine will have theirspeed increased, because my improved machine Will save all llllZGII'llPtion of their attention to copycaused by: using the hand lever to put upthe assembling-elevator and the time while the elevator is passing upand back will enable them'to be i the assembling-elevator, devices forconnectin the assemblin elevator with ower mechanism, a deviceiorantomatically disconnecting the elevator from the power mech- Y anrsm,and a counter device tor regulating the return movement of the elevator.
